T 0 all whom it may concern:

Be it known that I ALBERT I. GOLDMAN,

a citizen of the United States of America, residing at Chillicothe inthe county of Peoria and State of Illinois, have invented certain newand useful Improvements in Car-Couplers, of which the following is aspecification.

My invention relates to certain new and useful improvements in carcouplers and has for its obj ect the construction and combination ofparts in form and substance to cause the draft to be thrown upon themain body parts of the car coupler and to relieve the pivot pin betweenthe knuckle and the head from strain; to provide a perfectly closed headat the top to prevent the entrance of foreign substances; to provide alock set for the coupler pin whereby it may be lodged and held withoutthe operator being required to maintain hold upon the operating leverand to provide means for operating the coupler parts either from theside or top of thecar, and other details of novelty in combination whichare hereinafter fully set forth.

That my invention may be more fully understood, reference is had to theaccompanying drawings, in which Figure l is a front elevation of mycoupling showing its connection with a car body; Fig. 1 is also a frontelevation of my device showing a modified form of connection foroperating the coupling parts. Fig. 2 is a top plan View shown inconnection with the body of a car; Fig. 3 is a perspective view showingthe knuckle and arm connection; Fig. 4: is a front elevation showingportions broken away and also showing in solid and dotted lines twopositions of adjustment of parts of the coupler. Fig. 5 is a verticalsection through the center of the coupler taken from the left hand sideof the same; Fig. 6 is also a vertical sectional View taken from theright hand side of the coupler; Fig. 7 is a detail perspective view ofan ear portion of the coupler head; Fig. 8 is a detail perspective Viewof the coupler pin or block; Fig. 9 is a detail perspective view of abar designed to connect the coupler pin or block with the mechanism forshifting the block or pin; and, Fig. 10 is a detail perspective view ofa modified form of lever designed for use in connection with theshifting parts of the Specification of Letters Patent.

coupler. Fig. 11 is a perspective view of the knuckle showing partsbroken away.

In these drawings, A represents the draw bar provided with a couplerhead A and is suitably recessed as shown, to receive certain workingparts and within said recess are provided the shoulders a a, see Fig. 5,also one of the shoulders appearing in Fig. 4:.

The knuckle B is pivoted to ears projecting from the draw head as shown,by means of the pin B and is adapted to be forced open by an actuatingspring when free to move, which said actuating spring B shown in Fig. 7is coiled around the pivot pin B one end of the same being carriedwithin a recess 13* and the other end carried within the slot B the armof the spring which bears in slot B bearing somewhat above the face ofthe ear portion 13 of the upper head and is adapted to engage the recessB within the hub portion of the knuckle (such recessed portion beinshown in Fig. 1.1) so as to produce tension on the knuckle as it isclosed. The knuckle proper is provided with the elongated portion C,being that portion below the curvature shown in Fig. 3 and is providedwith the flange or lug projection C which flange or lug projection isprovided as a stop to prevent the coacting corresponding parts fromslipping past each other while coupled by reason of unevenness in theheight of cars or irregularity in the road bed and also to preventdropping out and falling upon the ground of the coupler. It will readilybe seen that the coacting parts or couplers being secured together andlocked, that if one of them should be pulled out from the body of thecar it cannot slip out but rests upon the ledge C Integral with theknuckle is the arm D projecting substantially at rightangles with theface thereof and is provided with the shoulders as d, as shown in Fig.3, there being a corresponding shoulder on the lower face of the arm inidentically the same relative location. This arm as will be understood,is adapted to extend within the cavity in the draw head and when theknuckle is closed, the shoulders d on the said arm will engage theshoulders or, in the draw head and the. said shoulder engagements willsustain the draft or pull between the cars thereby relieving the pinfrom strain.

To lock the knuckle in closed position, I

have providedjthe block or pin E which, is

housed in the casing E as best shown in I or pocket for the purpose ofalternately re-,

leasing or engaging the arm D of the knuckle.

F is a bar adapted to be carried within the channel F formed in the bodyof the draw head. The channel may be best seen by reference to Fig.6.The bar is provided with the finger projection F which is adapted toengage Wlth the opening E in block The lower end of the bar depends froman opening in the bottom of the draw head and is suitably pivoted to thearm G, which arm is also pivoted to' the draw head as at I. The directconnection between the bar F and the arm G is by the arcuate slot Jwhich facilitates the coaction of the two arms so that as arm G israised into the position shown in dotted lines by the operator drawingoutwardly upon the rodK, the bar F will be elevated into the positionshown in dotted lines carrying with it the block E and in such movementthe connecting pin 9 between the two arms will move rearwardly in theslot,

In the operation of the parts, it is desired that when the locking blockis raised, to disen age the arm D of the knuckle, that it may besustained in such elevated position without the operator being requiredto maintain his hold upon'the rod K or other means that may be providedto manipulate the parts referred to. v

To accomplish the above specified object, the bar F is provided with thelaterally extending shoulder 7 which is channeled out as at m and thereis also provided the tapered projection n at the forward end of theshoulder inclining rearwardly to the lower:

portion of the channel, also there is provided the notch z in thebarjust above the lug f which is of sufiicient size to embrace the lowerwall A of the draw head. By the 1 formation of the bar as abovespecified, as; the bar is elevated and as it approaches the 1 maximumlimit of such elevation, the rounded portionor elbow e will engage thetapered projection n at its maximum forward part and as the elbow passesupwardly and to the bottom of the channel N, the

bar F will be forced forwardly so as to of advantage.

head, which permits suflicient thereby unlocking the couplers so thatcars, I

coupler in the same opened condition by.

contact, will cause the arm D to be pushed rearwardly and in being sopushed rearwardly, the forward end VD thereof will, on account of therelative arrangement of the arm D with the bar F strike the inner faceof said reach, pushing it rearwardly a sufficient distance for it toclear the edge of wall A of the draw head, this disengagement of thesaid bar from the lock set position being accomplished just as the arm'D has reached the point in its movement into the recess within thedrawrhead that accomplishes the'proper engagement of the coactingknuckles for the proper coupling of the parts together and just at thispoint-{the locking block E will by force of gravity drop downwardly andin front of the face D of the arm D, thereby locking the parts together.7

I close the top of the draw head com pletely to prevent foreignsubstances from becoming lodged within the coupler head which, ifpermitted to do so, wouldrdestroy the efficiency'of'the coupler. Bymeans of forming the coupler head in themanner herein shown and freefrom all upward projections from the upper face of the head, I am ableto use. this coupler in connection with passengercoaches, which is afeature "In connection withFigl l, I have shown a modified form ofconnection for operating the locking block, the same being shown indotted lines and consists of a lever M shown in Fig-1O which ispivotedto the draw head as at O and also to the bar F as at Sand-thechain is provided for operating the'same. An elongated slot V isprovided in lever M at its pivotal connection with the draw lay toenable'the bar to be shifted to and rawn from its proper lock setposition. In theme of this character of connection for shifting thelocking block, it is designed to be-applied where it is desirable tooperate the coupler to be locked and unlocked from a point above thesame, as for instance, where the coupling connection must lead to aswitch engine or to the top of a car;

It is obvious that my invention may be embodied in different form fromthat shown herein, without departing from the spirit of my invention.

Having thus fully described my invention,
